Apply anti-corrosion oil to the thread and seat of new drive pin-
ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Never reuse drive pinion lock nut.
5.
Tighten to drive pinion lock nut, while adjust total preload torque.
CAUTION:
• Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
• If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
6.
Set a dial indicator (A) vertically to the tip of the drive pinion.
7.
Rotate drive pinion to check for runout.
• If the runout value is still outside of the limit after the phase
has been changed, possible cause will be an assembly mal-
function of drive pinion and pinion bearing and malfunction of
pinion bearing. Check for these items and repair if necessary.
8.
Make a stamping for identification of front oil seal replacement frequency. Refer to “Identification stamp of
replacement frequency of front oil seal”.
CAUTION:
Never make a stamping after replacing front oil seal.
9.
Install propeller shaft. Refer to

NOTE:
When installation is completed, driving sound of the side flange
turns into a sound which seems to affect the whole final drive.
A: Preload gauge [SST: ST3127S000 (J-25765-A)]

: Total preload torque
should equal the measure-
ment taken during removal
plus an additional 0.1 – 0.4
N·m (0.01 – 0.04 kg-m, 1 – 3
in-lb).
